Abstract

The round baler has a storage section (14) for excess baler chain (2). This is fitted with a tensioning arm (19), on which a chain guide roller (18) is mounted and which is connected to a spring (13). This limits expansion at the end of bale formation and exerts an inner pressure during bale compression.

Description

Die Erfindung betrifft eine Maschine zum Aufnehmen und Pressen von landwirtschaftlichem Erntegut mit einer von zumindest einer Ballenformeinrichtung gebildeten, aufklappbaren Wickelkammer zur Erzeugung eines Ballens, wobei die Ballenformeinrichtung über zumindest eine ortsfeste Antriebsrolle geführt ist und während einer Ballenformphase eine Wickelkammer ausbildet, welche sich von einer ein geringes Volumen an Erntegut aufnehmenden Größe in eine ein größeres Volumen aufnehmende Größe ausdehnen kann und mit einem Speicher zum Ausgleich des überschüssigen Teils der Ballenformeinrichtung versehen ist.The invention relates to a machine for picking up and pressing of agricultural crop with a formed by at least one bale forming device, hinged winding chamber for producing a bale, wherein the bale forming device is guided over at least one stationary drive roller and during a bale forming phase forms a winding chamber, which is from a small volume of crop receiving size can expand into a larger volume receiving size and is provided with a memory to compensate for the excess part of the bale forming device.

Aus der US 3,901,007 ist eine Ballenpresse bekannt, bei der ein Erntegutballen in einer Wickelkammer durch Anlage an zwei sich bewegenden Teilen einer Ballen-formeinrichtung gebildet wird. Einer dieser beiden Wickelbodenabschnitte, der durch einen endlos umlaufenden Wickelbodenteil gebildet wird, ist nachgiebig gestaltet. Da bei wachsendem Erntegutballen die Anlagefläche des Wickelbodens an dem Erntegutballen vergrößert wird, ist es notwendig, den zusätzlich benötigten Wickelboden aus einem Wickelbodenspeicher nachzuliefern. Dieser besteht aus schwenkbaren Umlenkeinrichtungen, der gegen eine, letztendlich eine Presskraft auf den Erntegutballen ausübende Spannkraft verschwenkt wird und damit Wickelboden freigibt. Die beschriebene Ballenformeinrichtung der US 3,901,007 ist konstruktiv aufwendig und somit nur zeit- und kostenintensiv zu bauen.From the US 3,901,007 a baler is known in which a Erntegutballen is formed in a winding chamber by conditioning on two moving parts of a bale-forming device. One of these two winding base sections, which is formed by an endlessly revolving winding base part, is made pliable. Since the contact surface of the winding base on the Erntegutballen is increased with increasing Erntegutballen, it is necessary to nachzuliefern the additionally required changing bottom from a winding floor storage. This consists of pivotable deflection, which is pivoted against a, finally a pressing force on the Erntegutballen exerting clamping force and thus releases winding bottom. The described Ballenformeinrichtung the US 3,901,007 is structurally complex and thus only time-consuming and costly to build.

Aus der WO 9730550 A1 ist eine Rundballenpresse mit veränderlichem Pressraum bekannt geworden, bei der sich der Pressraum ausgehend von einem kleinen Ballenkernbildungsraum bis hin zu seiner maximalen Größe ausdehnen kann. Während der Ballenbildung ist es zur Vergrößerung des veränderlichen Pressraumes erforderlich, dass weitere Riemenlänge aus einer Speichereinrichtung zur Umgrenzung des entstehenden Rundballens frei zu geben ist. Dazu sind in der WO 9730550 A1 ein primärer und ein sekundärer Riemenspanner vorgesehen, die die Riemen in unterschiedlichen Kombinationsmöglichkeiten mit einer Presskraft beaufschlagen. Dabei ist es z. B. vorgesehen, einen Rundballen mit einem weicheren Kern herzustellen. Weiterhin sind verschiedenartige Kompressionsprogramme offenbart, die beispielsweise eine konstante Presskraft oder eine allmählich ansteigende Presskraft auf die den Pressraum umgebenden Riemen ausüben. Ebenso gibt die WO 9730550 A1 Aufschluss darüber, dass durch eine veränderliche Gestaltung der Größe des Ballenkernbildungsraumes der weiche Kem eines Rundballens unterschiedliche Durchmesser aufweisen kann und somit eine verbesserte Eignung zur Verdichtung unterschiedlichster Erntegüter gegeben ist. Nach dem Ballenkernbildungsprozess unterliegt aber auch die hier beschriebene Rundballenpresse der Funktionsweise, bei der die auf den zu formenden Rundballen einwirkende Presskraft so eingestellt bzw. vorgegeben ist, dass jederzeit die weitere Ballenbildung beendet und ein fertiger Rundballen ausgeworfen werden kann. Die Herstellung auch solcher Rundballenpressen erfordert einen hohen konstruktiven Aufwand, der verständlicherweise auch mit hohen Kosten verbunden ist.From the WO 9730550 A1 has become known a round baler with variable pressing space, in which the pressing space can extend from a small bale formation space to its maximum size. During the formation of bales, in order to enlarge the variable pressing space, it is necessary for further belt length to be released from a storage device for defining the resulting round bale. These are in the WO 9730550 A1 a primary and a secondary belt tensioner are provided, which act on the belts in different combinations with a pressing force. It is z. B. intended to produce a round bale with a softer core. Furthermore, various compression programs are disclosed which, for example, exert a constant pressing force or a gradually increasing pressing force on the belt surrounding the pressing space. Likewise, the WO 9730550 A1 Information about the fact that the soft core of a round bale can have different diameters due to a variable design of the size of the bale core forming space and thus an improved suitability for compacting a wide variety of crops. After the bale core forming process, however, the round baler described here is also subject to the mode of operation in which the pressing force acting on the round bale to be formed is set or predetermined so that the further formation of bales can be stopped at any time and a finished round bale can be ejected. The production of such round balers requires a high design effort, which is understandably associated with high costs.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine verbesserte Maschine nach dem Oberbegriff des Anspruchs 1 zu schaffen, welche sich durch eine baulich einfache Ballenformeinrichtung auszeichnet und dennoch für verschiedenen Ballengrößen anwendbar ist.The present invention has for its object to provide an improved machine according to the preamble of claim 1, which is characterized by a structurally simple bale forming device and is still applicable to different bale sizes.

Die Aufgabe wird gelöst durch eine Maschine nach dem Oberbegriff des Anspruchs 1, welche sich dadurch auszeichnet, dass der Speicher eine den Ausschlag des Spannarms begrenzende Anschlagvorrichtung aufweist, so dass über die Anschlagvorrichtung mit einem Widerlager eine Begrenzung der weiteren Ausdehnung der Wickelkammer einleitbar ist und dass nach der Ballenformphase auf den Ballen in der Wickelkammer eine nach einem einstellbaren größeren Volumen aufbaubare Verdichtungskraft von außen nach innen durch die Ballenformeinrichtung ausgeübt wird. Entsprechend erfolgt die Freigabe einer Länge der Ballenformeinrichtung hier nur bis zum Erreichen eines vorgebbaren Durchmessers des Emtegutballens und nach Erreichen dieses Durchmessers wird von außen ein Pressdruck auf den Erntegutballen ausgeübt, der für die Verdichtung des Erntegutballens von außen nach innen sorgt.The object is achieved by a machine according to the preamble of claim 1, which is characterized in that the memory a limiting device of the clamping arm stop device has, so that on the stop device with an abutment limiting the further expansion of the winding chamber can be introduced and that after the bale forming phase on the bale in the winding chamber after a settable larger volume buildable compression force from outside to inside the bale forming device is exercised. Accordingly, the release of a length of the bale shaping device takes place here only until reaching a predetermined diameter of the Emtegutballens and after reaching this diameter, a pressing pressure is exerted on the Erntegutballen from the outside, which ensures the compaction of Erntegutballens from outside to inside.

Anders als bei den bestehenden Maschinen zum Aufnehmen und Pressen von landwirtschaftlichem Erntegut, die nach dem sogenannten Festkammerprinzip arbeiten, ist hier zum einen ein Durchmesser vorgebbar und zum anderen durch die ständige Anlage der Ballenformeinrichtung an den Erntegutballen eine gute Führung und damit eine gute Wickelung des Erntegutballens zu erreichen, ohne dass damit die im Stand der Technik beschriebenen Nachteile auftreten. So wird bei der erfindungsgemäßen Maschine bei jedem vorgebbaren Durchmesser ein Erntegutballen erzeugt, der sich durch eine von außen nach innen fortsetzende Verdichtung und damit durch formstabile Ballen mit sehr hoher Pressdichte auszeichnen.Unlike the existing machines for picking and pressing of agricultural crops, which operate on the so-called fixed chamber principle, here on the one hand a diameter can be specified and on the other hand by the constant investment of the bale forming device on the Erntegutballen good guidance and thus good winding of the Erntegutballens to achieve without the disadvantages described in the prior art occur. Thus, in the case of the machine according to the invention, a crop bale is produced at every predeterminable diameter, which bales are characterized by a compaction which continues from the outside to the inside and thus by a dimensionally stable bale with a very high compacting density.

Vorteilhafterweise weist die Spannvorrichtung des Speichers zumindest einen Kraftspeicher in Form eines Federelements auf. Durch die Verwendung eines dergestalt ausgebildeten Kraftspeichers verbilligt sich der Betrieb der Ballenformeinrichtung einer erfindungsgemäßen Maschine, da die früher üblichen, für die Aufbringung eines kontinuierlich großen Pressdrucks auf den Erntegutballen zu verwendenden und entsprechend groß dimensionierten Federelemente oder Zylinder hier entfallen können. Aufgabe des Kraftspeichers ist es lediglich, die Ballenformeinrichtung mit einer Schlupf zwischen Antriebsrolle und Ballenformeinrichtung vermeidenden Spannkraft zu beaufschlagen. Es ist auch denkbar, statt eines Federelements einen einfachen Zylinder zu verwenden.Advantageously, the clamping device of the memory has at least one energy store in the form of a spring element. By using a force accumulator designed in this way, the operation of the bale forming device of a machine according to the invention becomes cheaper, since the earlier customary, for applying a continuously large pressing pressure on the Erntegutballen to be used and correspondingly large-sized spring elements or Cylinder can be omitted here. The task of the energy storage device is merely to pressurize the bale forming device with a slip force between the drive roller and the bale forming device, which avoids tensioning forces. It is also conceivable to use a simple cylinder instead of a spring element.

Für eine vorteilhafte Ausbildung der Erntegutballen ist es von besonderem Vorteil, wenn die Ballenformeinrichtung Antriebsriemen umfasst, welche an den äußeren Enden von Querstäben angebracht sind, wobei die Antriebsriemen ebenso wie eine Antriebsrolle an ihrer Oberfläche eine Querprofilierung aufweisen. Die Querprofilierung kann insbesondere zwischen Antriebsrolle und Antriebsriemen eine unterschiedliche Teilung aufweisen. Dadurch wird verhindert, dass sich Erntegut zwischen Antriebsriemen und Antriebsrolle anlagert, sondern statt dessen durch die verschiedene Teilung zerschnitten wird. Des weiteren werden die für den Betrieb der Ballenformeinrichtung notwendigen Kräfte durch eine wie eben beschriebene Ausgestaltung der Ballenformeinrichtung gut übertragen.For an advantageous embodiment of the Erntegutballen, it is particularly advantageous if the bale forming device comprises drive belts which are attached to the outer ends of transverse bars, wherein the drive belt as well as a drive roller on its surface have a transverse profiling. The transverse profiling may in particular have a different pitch between the drive roller and the drive belt. This prevents crops from accumulating between the drive belt and the drive roller but instead being cut by the various pitches. Furthermore, the forces necessary for the operation of the bale forming device are well transferred by a design of the bale forming device as just described.

Eine erfindungsgemäße Maschine 1 zum Aufnehmen und Pressen von landwirtschaftlichem Erntegut weist eine größtenteils von einer Ballenformeinrichtung 2 umgebene und gebildete Wickelkammer 3 auf. Die Wickelkammer 3 selbst besitzt eine Einlassöffnung 4, durch die allgemein mit einer Aufnahmevorrichtung 6 aufgenommenes Erntegut wie beispielsweise Heu oder Anwelkgut in die Wickelkammer 3 befördert wird. Eine Antriebsrolle 7 unterteilt die Ballenformeinrichtung 2 in ein Lasttrum 8 und ein Leertrum 9, wobei sich das Lasttrum 8 von dem Leertrum 9 dadurch unterscheidet, dass es die Antriebskräfte auf den Erntegutballen überträgt. Beiderseits der Einlassöffnung 4 angeordnete Walzen 11 begrenzen zusätzlich die Wickelkammer 3. Zu Beginn eines Ballenformvorganges liegt das Lasttrum 8 der Ballenformeinrichtung 2 zusätzlich an eine Startkammer ausbildenden Führungsvorrichtungen 12 an. Bei diesem Ausführungsbeispiel sind die Führungsvorrichtung 12 als Umlenkrollen ausgebildet, es kann sich hierbei jedoch auch um Führungsflächen handeln.A machine 1 according to the invention for picking up and pressing agricultural crops has a winding chamber 3 largely surrounded and formed by a bale forming device 2. The winding chamber 3 itself has an inlet opening 4, is transported by the generally with a receiving device 6 recorded crop such as hay or Anwelkgut in the winding chamber 3. A drive roller 7 divides the bale forming device 2 into a load strand 8 and an empty strand 9, wherein the load strand 8 differs from the empty strand 9 in that it transfers the driving forces to the harvested material bales. Rollers 11 arranged on both sides of the inlet opening 4 additionally delimit the winding chamber 3. At the beginning of a bale forming operation, the load strand 8 of the bale forming device 2 is additionally in contact with guide devices 12 forming a starting chamber. In this embodiment, the guide device 12 are formed as pulleys, but this may also be guide surfaces.

Die Ballenformeinrichtung 2 wird mit Hilfe einer Spannvorrichtung 13.1 unter Spannung gehalten, wobei die Spannvorrichtung 13.1 einen Speicher 14 zur Aufnahme bzw. Abgabe von Teilen der Ballenformeinrichtung 2 umfasst und durch einen Kraftspeicher 13 mit einer Kraft beaufschlagt werden kann, welche eine nahezu schlupffreie Übertragung des erforderlichen Antriebsmomentes zwischen der Antriebsrolle 7 und der Ballenformeinrichtung 2 sicherstellt. Dadurch liegen die zwischen der Antriebsrolle 7 und einer Umlenkrolle 16 befindlichen Abschnitte des Lasttrums 8 der Ballenformeinrichtung 2, anders als in Fig. 1 dargestellt, parallel zu den Seitenkanten 17 der die Wickelkammer 3 begrenzenden Führungsseitenwände.The bale forming device 2 is held under tension with the aid of a tensioning device 13.1, wherein the tensioning device 13.1 comprises a memory 14 for receiving or dispensing parts of the bale forming device 2 and can be acted upon by a force memory 13 with a force which permits a virtually slip-free transmission of the required Drive torque between the drive roller 7 and the bale forming device 2 ensures. As a result, located between the drive roller 7 and a guide roller 16 are portions of the load strand 8 of the bale forming device 2, unlike in Fig. 1 shown, parallel to the side edges 17 of the winding chamber 3 limiting guide side walls.

Der Speicher 14 weist im wesentlichen einen mit einer Umlenkrolle 18 versehenen Spannarm 19 auf, an den der als Federelement ausgebildete Kraftspeicher 13 angreift. Füllt sich die Wickelkammer 3, so wird ein nach außen gerichteter Druck auf das Lasttrum 8 ausgeübt und das Federelement wird gestaucht. Dabei ändert sich die zwischen den Umlenkrollen 21 und 18 befindliche Länge der Ballenformeinrichtung 2 und die Erntegutballenvergrößerung geht einher mit einer Vergrößerung der Wickelkammer 3.The memory 14 essentially has a tensioning roller 19 provided with a deflection roller 18, to which the force accumulator 13 designed as a spring element engages. If the winding chamber 3 is filled, an outwardly directed pressure is exerted on the load strand 8 and the spring element is compressed. In this case, the length of the bale forming device 2 located between the deflection rollers 21 and 18 changes and the Erntegutballenvergrößerung goes along with an enlargement of the winding chamber. 3

Eine einstellbare Begrenzungsvorrichtung zur Vorgabe eines Durchmessers des Erntegutballens ist bei diesem Ausführungsbeispiel der Erfindung als relativ zum Spannarm 19 schwenkbare Anschlagvorrichtung 22 ausgebildet, die in ein gehäusefestes Widerlager 23 eingreift. Je nach Relativposition der Anschlagvorrichtung 22 zum Spannarm 19, d. h. je nach Winkel, der zwischen der Längsachse des Spannarms 19 und der Längsachse der Anschlagvorrichtung 22 eingestellt ist, greift eine der mehreren Aufnahmen der Anschlagvorrichtung 22 in das Widerlager 23 ein und begrenzt somit die Länge der Ballenformeinrichtung 2, die von dem Speicher 14 zur Vergrößerung der Wickelkammer 3 zur Verfügung gestellt wird. Auf diese Art und Weise ist eine sehr kostengünstige und wartungseinfache Vorrichtung zur Vorgabe eines Durchmessers des Erntegutballens geschaffen.An adjustable limiting device for specifying a diameter of the Erntegutballens is formed in this embodiment of the invention as a relative to the clamping arm 19 pivotable stop device 22 which engages in a fixed housing abutment 23. Depending on the relative position of the stop device 22 to the clamping arm 19, d. H. Depending on the angle, which is set between the longitudinal axis of the clamping arm 19 and the longitudinal axis of the stop device 22, engages one of the several shots of the stop device 22 in the abutment 23 and thus limits the length of the bale forming device 2, of the memory 14 to increase the Winding chamber 3 is provided. In this way, a very inexpensive and easy to maintain device for specifying a diameter of the Erntegutballens is created.

Da die Führungsvorrichtungen 12 nicht in die anfangs gebildete Wickelkammer 3 der erfindungsgemäßen Maschine 1 eingreifen, steht zu Beginn eines Ballenformvorgangs eine im Querschnitt in etwa fünfeckige Startkammer zur Verfügung. Dies beeinflusst die Bildung eines Erntegutballenkerns positiv, da ausreichend Platz zur Verfügung steht, eine Initialrotation des in die Wickelkammer 3 beförderten Ernteguts hervorzurufen. Gleichzeitig wird das Erntegut aufgrund des Polygoneffektes gut durchgewalkt, da das gemäß Fig. 1 entlang des die Wickelkammer 3 begrenzenden fünfeckigen Randes beförderte Erntegut phasenweise gestaucht wird. Das durch die Einlassöffnung 4 in die Wickelkammer 3 transportierte Material fällt bevorzugt in den in Fahrtrichtung hinteren Teil der Wickelkammer 3 und wird durch das Lasttrum 8 in eine Rotation entgegen dem Uhrzeigersinn versetzt. Dieses entspricht in etwa auch dem Start des Wickelvorgangs bei einer Erntegutballenpresse nach dem sogenannten Festkammerprinzip. Gleichwohl ist der Speicher 14 so nachgiebig ausgelegt, dass sich die Wickelkammer 3 während ihrer Befüllung erweitern kann und die Ballenformeinrichtung 2 beispielsweise in die in Fig. 1 dargestellte Position überführt wird.Since the guide devices 12 do not engage in the initially formed winding chamber 3 of the machine 1 according to the invention, at the beginning of a bale forming process, an approximately pentagonal starting chamber is available. This positively affects the formation of a crop bale since sufficient space is available to cause an initial rotation of the crop being conveyed into the wrap chamber 3. At the same time the crop is well durchgewalkt due to the polygonal effect, since the according Fig. 1 along the winding chamber 3 bounding pentagonal edge conveyed crop is compressed in phases. The material transported through the inlet opening 4 into the winding chamber 3 preferably falls in the direction of travel in the rear part of the winding chamber 3 and is offset by the load strand 8 in a counterclockwise rotation. This corresponds approximately to the start of the winding process in a Erntegutballenpresse according to the so-called fixed chamber principle. However, the memory 14 is designed so yielding that the winding chamber 3 can expand during its filling and the bale forming device 2, for example, in the in Fig. 1 shown position is transferred.

Hierbei ist es von Vorteil, dass aufgrund der nachgiebigen Anlage des in die Wickelkammer 3 hineinbeförderten Ernteguts an der Ballenformeinrichtung 2 ein guter Kontakt zwischen dieser und dem Erntegut realisiert wird, jedoch dieses bei gleichzeitig weitgehender Vermeidung eines Pressdrucks geschieht. Es bleibt somit bei einem vergleichsweise locker gewickelten Emtegutballen. Erst dann, wenn wie in Fig. 1 gezeigt, die Anschlagvorrichtung 22 mit dem Widerlager 23 in Eingriff steht, wird die weitere Ausdehnung der Wickelkammer 3 begrenzt und es baut sich bei weiter zugeführtem Material ein hoher Pressdruck auf, der ausgehend von der äußeren Schicht des Erntegutballens diesen bis hin zum Ballenkern verdichtet.In this case, it is advantageous that due to the resilient installation of the harvested material conveyed into the winding chamber 3 on the bale forming device 2, a good contact between the latter and the crop is realized, but this at the same time largely avoiding Pressing happens. It thus remains with a comparatively loosely wound Emtegutballen. Only then, if as in Fig. 1 shown, the stopper 22 is in engagement with the abutment 23, the further expansion of the winding chamber 3 is limited and it builds on further supplied material, a high pressure, which compresses from the outer layer of the Erntegutballens this up to the bale core.

Insgesamt ist so eine Maschine 1 zum Aufnehmen und Pressen von landwirtschaftlichem Erntegut geschaffen, die Erntegutballen variabler Größen herstellen kann, diese jedoch im Unterschied zu den bisherigen variablen Maschinen eine Ballenstruktur aufweisen, die ähnlich denen einer Festkammermaschine sind.Overall, such a machine 1 for picking and pressing of agricultural crop is created that can produce crop bales of variable sizes, but these have in contrast to the previous variable machines a bale structure, which are similar to those of a fixed-chamber machine.

Vorteilhafterweise ist die zum Speicher 14 gehörende Umlenkrolle 18 in Fahrtrichtung vor dem hinteren Ende der Maschine und hinter dem Zentrum des sich bildenden Erntegutballens angeordnet. Hierdurch baut die erfindungsgemäße Maschine 1 sehr kompakt.Advantageously, the deflection roller 18 belonging to the storage 14 is arranged in the direction of travel in front of the rear end of the machine and behind the center of the forming crop bale. As a result, the machine 1 according to the invention is very compact.

Weiterhin ist es von Vorteil, wenn der Spannarm 19 des Speichers 14, bzw. der Spannvorrichtung 13.1 in Bezug zu einer zwischen einer Anlenkstelle des Spannarms 19 am Maschinerahmen und einer Drehachse 24 der Umlenkrolle (18) sich erstreckenden Bezugsebene in einem Winkel von 60 bis 120° kraftbeaufschlagbar ist. Die in Fig. 1 abgebildete Kraftbeaufschlagung durch das Federelement bzw. den Kraftspeicher 13 ist somit in etwa rechtwinklig zum Spannarm, was einen guten Hebelarm und somit eine gute Übertragung der vom Kraftspeicher 13 aufgebrachten Kräfte bedeutet. Idealerweise ist die Ausrichtung des Kraftspeichers 13 so gewählt, dass diese der Winkelhalbierenden der durch die Umlenkrolle 18 umgelenkten Riementrums entspricht. Weiterhin greift der Kraftspeicher 13 in der Nähe der Umlenkrolle 18 an den Spannarm 19 an, und damit in einem Bereich, in dem die von der Ballenformeinrichtung 2 auf den Spannarm 19 aufgebrachten Kräfte anliegen, wodurch die resultierenden der von der Ballenformeinrichtung 2 einwirkenden Kräfte durch die Anschlagvorrichtung 22 und den Spannarm 19 gut abgestützt ist. Die von der Ballenformeinrichtung 2 auf die Umlenkrolle 18 übertragenen Kräfte werden über die Anschlagvorrichtung 22 und das Widerlager 23 einerseits und den Spannarm 19 andererseits direkt in das Gehäuse geleitet, was eine besonders feste Abstützung gewährleistet.Furthermore, it is advantageous if the clamping arm 19 of the memory 14, or the clamping device 13.1 with respect to a between a pivot point of the clamping arm 19 on the machine frame and a rotation axis 24 of the guide roller (18) extending reference plane at an angle of 60 to 120 ° kraftbeaufschlagbar is. In the Fig. 1 shown force applied by the spring element or the energy storage 13 is thus approximately at right angles to the clamping arm, which means a good lever arm and thus a good transfer of the force accumulator 13 applied forces. Ideally, the orientation of the force accumulator 13 is selected so that it corresponds to the bisector of the deflected by the guide roller 18 belt. Furthermore, the energy accumulator 13 engages in the vicinity of the guide roller 18 to the clamping arm 19, and thus in a region in which abut the forces applied by the bale forming device 2 on the clamping arm 19, whereby the resulting forces acting from the bale forming device 2 by the Stop device 22 and the clamping arm 19 is well supported. The transmitted from the bale forming device 2 on the guide roller 18 forces on the stopper 22 and the abutment 23 on the one hand and the clamping arm 19 on the other led directly into the housing, which ensures a particularly firm support.

Es liegt im Rahmen der Erfindung, dass die Anschlagvorrichtung mit ihren die Aufnahmen ausbildenden Nasen 26 bei gleicher Funktionalität anders ausgebildet sein kann. Die Anschlagvorrichtung 22 muss hierfür lediglich die Verschwenkung des Spannarms 19 blockieren, durch die für die Wickelkammer 3 Teile der Ballenformeinrichtung 2 freigegeben werden. Hierbei kann es sich selbstverständlich auch um stufenlos einstellbare Anschläge handeln oder um an anderen Stellen eingreifende Blockiervorrichtungen, beispielsweise kann das Widerlager 23 ebenfalls als schwenkbar am Gehäuse befestigter Arm ausgebildet sein, der in verschiedene Punkte des Spannarms 19 eingreift und damit einen Durchmesser des Erntegutballens vorgibt.It is within the scope of the invention that the stop device may be formed differently with their receptacles forming noses 26 for the same functionality. For this purpose, the stop device 22 only has to block the pivoting of the tensioning arm 19, by which parts of the bale forming device 2 are released for the winding chamber 3. This may of course also be infinitely adjustable stops or at other locations engaging blocking devices, for example, the abutment 23 may also be formed as a pivotally mounted on the housing arm, which engages in different points of the clamping arm 19 and thus dictates a diameter of the Erntegutballens.

Die in Fig. 2 dargestellte Ausführungsform einer erfindungsgemäßen Maschine zeigt die maximale Größe der Wickelkammer 3, was durch den kreisbogenförmigen Abschnitt des Lasttrums 8 angedeutet wird, da der Speicher 14 die maximal mögliche Länge der Ballenformeinrichtung 2 freigegeben hat. Auch in dieser Zeichnung befindet sich die Anschlagvorrichtung 22 in Eingriff mit dem Widerlager 23, so dass keine weitere Länge der Ballenformeinrichtung 2 freigegeben werden kann.In the Fig. 2 illustrated embodiment of a machine according to the invention shows the maximum size of the winding chamber 3, which is indicated by the circular arc-shaped portion of the load section 8, since the memory 14 has released the maximum possible length of the bale forming device 2. Also in this drawing, the stopper device 22 is in engagement with the abutment 23, so that no further length of the bale forming device 2 can be released.

Des weiteren ist vorgesehen, wie dies auch die Figuren 3 und 4 näher verdeutlichen, dass die Ballenformeinrichtung 2 die ihren jeweiligen Seitenbereichen Tragriemen hat, an denen Querstäbe 2.2 befestigt sind. Diese sind von den Umlenkrollen 12 geführt. Damit ist ein außerordentlich leiser Betrieb der Ballenformeinrichtung ermöglicht.Furthermore, it is provided, as well as the Figures 3 and 4 make it clearer that the bale forming device 2 has its respective side regions carrying strap, on which cross bars 2.2 are attached. These are guided by the pulleys 12. This allows extremely quiet operation of the bale forming device.

Die erfindungsgemäße Maschine 1 weist in dem in Fig. 3 beschriebenen Ausführungsbeispiel zusätzlich zu der Anschlagvorrichtung 22 einen Stellarm 28 mit Ausnehmungen 29 auf, die für eine Arretierung der Anschlagvorrichtung 22 in den beschriebenen unterschiedlichen Winkelpositionen bezüglich des Spannarms 19 Sorge tragen. Hierfür greift eine Befestigung 30, die bei diesem Ausführungsbeispiel an der Anschlagvorrichtung 22 angebracht ist, lösbar in die Ausnehmungen 29 und arretiert somit die Anschlagvorrichtung 22 in den unterschiedlichen Positionen. Das Widerlager 23 weist weiterhin einen Hebelarm 31 auf, der zusammen mit einer am Gehäuse festgelegten Feder 32 die gehäusefeste Abstützung bildet. Durch die Feder 32 ist eine Beweglichkeit des Hebelarms 31 um seine Schwenkachse 31.1 gewährleistet, so dass innerhalb eines vorgebbaren Bereiches unter Mithilfe von mechanischen, elektromechanischen oder auch anderen Mitteln 33 der auf den Erntegutballen wirkende Pressdruck überprüft werden kann. In der in Fig. 4 abgebildeten Darstellung der Anschlagvorrichtung 22 ist das Widerlager 23 in Eingriff mit der obersten, durch die Nase 26 gebildeten Ausnehmung. Dieses entspricht einem Erntegutballendurchmesser, wie er in Fig. 2 durch den großen Umfang der Ballenformeinrichtung in der Wickelkammer 3 angedeutet ist.The inventive machine 1 has in the in Fig. 3 described embodiment, in addition to the stop device 22 on an actuating arm 28 with recesses 29, which carry for a locking of the stop device 22 in the described different angular positions with respect to the clamping arm 19 care. For this purpose, a fastening 30, which is attached to the stop device 22 in this embodiment, releasably engages in the recesses 29 and thus locks the stop device 22 in the different Positions. The abutment 23 further comprises a lever arm 31 which forms the housing-fixed support together with a spring 32 fixed to the housing. By the spring 32 a mobility of the lever arm 31 is ensured about its pivot axis 31.1, so that within a predetermined range with the help of mechanical, electro-mechanical or other means 33 of the force acting on the Erntegutballen pressing pressure can be checked. In the in Fig. 4 shown representation of the stopper 22, the abutment 23 is in engagement with the uppermost, formed by the nose 26 recess. This corresponds to a crop bale diameter, as in Fig. 2 is indicated by the large circumference of the bale forming device in the winding chamber 3.
